INFEASIBLE SOLUTION: LP models with inconsistent constraints have no feasible solution. This situation does not occur if all the constraints are of the type with nonnegative right-hand sides because the slacks provide an obvious feasible solution. For other types of constraints, penalized artificial variables are used to start the solution. If at least one artificial variable is positive in the optimum iteration, then the LP has no feasible solution. maximize 3 - xy + 2. X2 (14) Subject to: *1 + x2
